What's the other options besides hg if it ain't git?

[Shorel]

SQLite uses Fossil.

[MayeulC]

Bazaar used to be an option: http://bazaar.canonical.com/en/

Pijul is very promising: https://pijul.org/ and https://pijul.org/manual/why_pijul.html

Merging A in B should yield the same result as the opposite with Pijul, etc.

darcs is still actively developed and it has a niche in the Haskell community.

Ubuntu might still use Bazaar.

BitKeeper is one, Fossil is another. Then there are non-DVCS systems like Subversion, Perforce, VSTS etc.

SVN still works well for our company.
